OIL-BURNER.

To'all whom it may concern Be it known that I, LYCURGUS E. Arr

nnosn, a citizen of the United States, and -a resident of the city of Mena, county of Polk,

and State of Arkansas, have invented certain new and useful Improvements in Oil- Burners, of which the following is a specification.

My invention relates to oil burners and 6 more specifically to that class thereof designed to be arranged inside a stove to burn a liquid hydro-carbon as the fuel by reducing it "to a' vapor or gaseous form and then mixing the fuel gas or vapor with air to form a combustible mixture.

The object of'my invention is the production of a burner of the character mentioned, which will be of durable and economical construction and eiiicient in use.

2 Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by 5 reference to the accompanying drawing forming a part of this specification, and in which, 7

Figure l is a perspective view of a burner embodying my invention, big. 2 is a vertical 3o transverse section of the burner, and Fig. 3 w is a detail fragmentary horizontal sectionillustrating the intersection of the fuel pipe with the mixing chamber of the burner.

The preferred form of construction com- ;prises a vaporizing or generating chamber 1 which is substantially U-shaped in form, one end of said chamber being connected with a liquid fuel supply pipe 2 which, in use, 'com-" municates with any suitable source of fuel supply.

Arranged directly below the vaporizing chamber 1 is a mixing chamber 3 in the form of an elongated cylinder or pipe, the corresponding ends of the members 1 and 3 being connected together'and held in spaced relation by a link or strap 4. The upper end' ofthe link 4 is connected with the member 1 by means of a pipe 5 the outer end of which is provided with a rem'oyable screw cap 6 through which 'ac'cess may be gained to the f interior of the chamber 1 to effect ready cleaning thereof. A similar screw cap 7 is 'rovided at the corresponding end of chamr 3 whereby access may be readily gained 55 to the latter to effect cleaning of the same.

her 1 is a fuel or vapor'conveying ipe 8 the lower end of which intersects t e corresponding end of the chamber 3 as clearly shown in' Figs. 2 and 3, pipe 8 being of a diameter considerably less than that of the interior of said mixing chamber so that air passages 9 will be formed in said mixing chamber at either side of said pipe. F orined in the pipe 8 is an orifice 1-" through which the fuel vapor is dischar ;ed from said pipe into-said mixing chamber.

The end of the mixing chamber 3 beyond pipe 8 is open to the outside atmosphere being equipped with a manually adjust-able regulating device 11 of any approved design, the arrangement being such that, in the operation of the burner airwill be admitted through the'devi'ce 11 for mixture with the vapor injected into said chamber through the orifice 10. The lower end of the pipe 8 is equipped with a removable screw cap 8 through which access may be ing the orifice 10 when desired. The upper .side of the mixing chamber 3 is provided with a plurality of spaced transversely extending slots or openings 12 through which the combustible mixture supplied to said chamber, during the operation of the device is discharged for combustion.

Arranged below the chamber 3 ,is an oil pan 13 rigidly secured in position by means of straps 14 which'er nbrace said chamber as clearly illustrated. Provided in the pan 13 at either side of chamber 3 are elongated openings 15 extending parallel with said cha'mber through which in the operation of *the burner air will be permitted to pass in order to supply additional oxygen to the gas escaping from openings 12 in order to afford complete combustion, whereby a maximum utilization of the fuel is obtained.

riphery of said pan are upwardly extending I flanges 16 which prevent overflowing of said pan when oil is supplied thereto as is the =case in the initial lighting of-the burner as set forth in the following.

In the operation of the'burner, the oil is first allowe to pass through the chamber 1, pipe 8 and c amber 3' so as to overflow into the pan 13 where the same is lighted. The heat of this combustion will convert the oil in the chamber 3 into vapor whichwill escape through the openings 12 of said chamber. Vapor thus escaping will mix with the airqarising through openings 15 and the mixture will burn directly under the vaporizing chamber with the effect 'of vaporizing the oil therein. After this initiallighting the oil fed to the chamber 1 from pipe 2 wi become vaporized in its passage there-J .through by reason'of the heat below and so that when the fuel reaches thepipe 8 it will be in a vaporous or gaseous state,being dise charged into the chamber-3 in this form to mix with the air supplied to said chamber 1 through the regulator 11. The orifice 1.0

through which the fuel vapor or gas is injected into the chamber 3 from pipe 8 being. so positioned in the latter that the air is ad-- mitted at the back tbereof,-the air passing through spaces 9 at either side of said pipe,

' a thorough mixture of the; air with the fuel gas or vapor is insured with a corresponding high degreeof efliciency of the burner. By reason of a perfect mixture which is thus.

' insured, the possibility of the heme creeping back in the chamber 3 to the air inlet openings, such as not infrequently occurs in burners of this character now in use, is obviated. In use-the burner will be so arranged in the stove that the air regulator 11 will be ositioned exteriorly so that adjust: ment 01 said regulator may be effected at any time in order to secure a perfect com-- bustible mixture. Y

Having described myinvention what I claim as new'and desire to secure by Letters. Patent is: I x

1. A burner of the class described compris- 5 'ing an oil pan; an elongated vaporizingchamber and an elongated mixing chamber arranged above said pan with said vaporiz mg chamber positioned above sa1d mixing chamber; a fuel supply communicat ng with 5 said vaporizing chamber; and-a pipe estab lishing communicationbetween corresponding ends of said vaporizing and mixing chambers, saidendzofsaid mixing chamber having air inlet openings, said.oil pan haw- 5,5 ing openingsthereinpositioned adjacent op-." 1

stantially as d scribed, I 2. A burner Of'fChBClfl-SS described compositejsides of said mixing chamber, subprising an oil pan; an elongated yaporizi'ng 1 chamber and an-elongated mixing chamber arranged abosze saidhpau with; said vaporizing chamber positioned above said mixing chamber; a fuel supplcommunicatingwvith said vaporizingcham er; .a pipe-establishing communication between corresponding ends of said' vaporizing. andcmixing chambers, said end of said-miringchamber having an- 1 nlet o en1ngs,'sa1d-o1l pan having openings theremfpositioned adjacentopposite sides of said mixing chamber; and upwa'rdly extending flanges surrounding said openings and provided atthe perlphery of said pan, substantially 35118561313851.
